Is there by anychance any cisco gear in front of the raptor? I fell into the same scenario a while back where the cisco 
was the actual problem and not the FW-1. If you have mapped the public ip's I suggest looking for one. Just a 
thought... ( i had to slow my scans down to the polite setting.. yikes was that slow.)

We've run a pentest against a customer recently and found that the very act
of port scanning their Raptor firewall (running on NT) crippled its ability
to accept incoming connections for their web site. The firewall is a new
high spec PIII and the least line is a decent size. The nmap scans were
standard timing (not T5 or anything daft) - once the scans were stopped,
things burst back in to life within about 10minutes.

Does this ring any bells with anyone? Seems very odd to me... a portscan
should not cause a DOS by itself...
